Big Jim, if you used a 42 circuit panel, obviously it had to be a 200 amp. panel. Did it have a main breaker? If so, were you not overloading the wire. If it was a main lug panel, did not the inspector question you on the amount of circuits you used for a 100 amp. service? Since the biggest 100 amp panel that I can get is 20 circuit, it seems that is all that is allowed for a 100 amp. service, to regulate how much of a load can be put on the panel. I am just asking just in case I am missing something here. Thanks for the reply. Steve
